The 8 KB SRAM budget limits buffered data to about 2 KB of TCP payload or a modest ADC scan table — so if your application needs a large frame buffer or extensive logging, this part will feel tight. ## Industrial temperature and 48-LQFP footprint The 48-LQFP (7x7 mm) package has 28 general-purpose I/O, an 8-channel 10-bit ADC, and internal oscillator — enough for a sensor hub or motor-drive interface without external clock components. ## Sourcing reality for a NRND part Because the LM3S608 is NRND, the authorized-distributor pipeline is winding down. Independent distribution carries remaining inventory and material from excess stock. Every unit we quote is verified against the manufacturer's marking and date-code consistency — the laser etch on the 48-LQFP body is a fingerprint we check against known-good TI production runs.","metaTitle":"LM3S608-IQN50-C2T ARM Cortex-M3 MCU, 50MHz, 32KB Flash, NRND","metaDescription":"Stellaris LM3S608-IQN50-C2T 32-bit ARM Cortex-M3 MCU at 50MHz with 32KB Flash, 8KB SRAM, 28 I/O, industrial temp.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Microcontrollers & Processors (MCU / MPU / DSP)"],"specifications":{"Mfr":"Texas Instruments","Speed":"50MHz","Series":"Stellaris® ARM® Cortex®-M3S 600","Package":"Tape & Reel (TR); Cut Tape (CT)","RAM Size":"8K x 8","Core Size":"32-Bit Single-Core","EEPROM Size":"-","Peripherals":"Brown-out Detect/Reset, POR, PWM, WDT","Connectivity":"I²C, Microwire, SPI, SSI, UART/USART","Mounting Type":"Surface Mount","Number of I/O":"28","Core Processor":"ARM® Cortex®-M3","Package / Case":"48-LQFP","Product Status":"Not For New Designs","Data Converters":"A/D 8x10b","Oscillator Type":"Internal","lifecycle_stage":"eol_hot","Base Product Number":"LM3S608","Program Memory Size":"32KB (32K x 8)","Program Memory Type":"FLASH","Operating Temperature":"-40°C~85°C(TA)","Supplier Device Package":"48-LQFP (7x7)","Voltage - Supply (Vcc/Vdd)":"3V ~ 3.6V"}},"commercial":{"minOrderQty":null,"leadTime":null,"referencePrice":"$8.9979","priceTiers":null},"links":{"datasheetUrl":"https://cdn.icboms.com/9109009f04d405b36e915a9797bfb924.pdf","sourceUrl":null,"alternativesUrl":"https://icboms.com/api/mcp/products/LM3S608-IQN50-C2T/alternatives.json"},"ai":{"faq":[{"question":"Is LM3S608-IQN50-C2T obsolete?","answer":"It is not fully discontinued, but it is no longer supported for new project starts.
